VERY Buggy & Hard to Figure Out

So buggy. Weird stuff like the up and down buttons to change font size go up or down several numbers with each click (instead of just 1) and when you select global font family choices from the dropdown menu, you have to click on the menu again to get the dropdown to go away. As others have mentioned, sometimes you have to save the draft to get the page to refresh and show changes. There are also several things that are impossible to figure out or not at all intuitive. I am a very advanced WP user, and can write html code. If I find this difficult to use, I can imagine how frustrated a newbie would be trying to figure it out. I am removing this plugin less than 30 minutes after installing.
